Just got my first 10-disk system set up and running, and wanted to dink with predicted temperature rises and final temp prediction.
For most simple thermal processes, they hit a final temp you can estimate by simple exponential settling. It's a lot more complex as everything about heat transfer changes with everything else, but simple exponential rise isn't all that bad.
It occurred to me that for setting up a new system, one could have the system tell you when it thought it was *going to* exceed some temp after it settled. This would be a pure PITA to be running all the time, but it's remarkably useful when you're setting up a new system to have it squawk at you that it thinks it's under-cooled.
I found the scripts to email temps, and then realized that this kind of output could be logged into a temp log file, then examined for prognostications about things going south. A cron job to sample temps every few minutes and simply write them onto the end of a log file would not be that hard to do ( and I'm working on that now) but having it do a sanity check for "hey, how hot am I going to get if this keeps up?" to let it send off a red-flag email would be a really nice system burn-in thing to have.
I speculate so, at least.
Working...
